Every Sunday morning, Opal, Lisa, Talia, and Cora meet for breakfast at the Bagel Shop. They share the bill equally and each pay $2 toward the tip. The expression 1/4x +2 represents
the amount each friend pays, where z is the amount of the bill before the tip.

z is going to be 8 dollars less than the GRAND TOTAL

Step-by-step explanation:

4 multiplied by 2=8.

the number 4 represents the amount of people in the problem.

the number 2 represents the tip amount that each person is paying.

the number 8 represents the total amount of the tip that they all COLLECTIVELY give the waiter.

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x
